Patent CA-2090249-C (CA)
Title: Module for automatically controlling a polymer processing system
Inventor: PARDIKES DENNIS G
IPC: B01F3/08
Filed: 1993-02-24
Granted: 2003-11-11
Abstract: A controller for a polymer processing system operates by emitting a controlled amplitude and frequency of coherent light (laser) energy which is scattered and absorbed by the monitored polymer dispersed throughout an instantaneous aqueous sample of a monitored material flowing continuously through a cross section of a sample chamber. The source of light energy is located an adjustable distance from one side of the sample chamber.      An optical receiver (a photoresistor with a selectable filter) measures the amount of light received on the other side of the sample chamber. An output signal of the receiver may be converted into a usable process signal which is then transmitted as an input control signal to a process controller (microprocessor or microcomputer). The process controller output and display can be configured to control and read in any suitable manner. When the monitored system has feedback, the receiver output may be applied through a feedback control loop. Active polymer solids or any other relevant engineering unit or scale, such as percent concentration, may be displayed. The receiver output signal may also operate any suitable controls of any other suitable system, such as in a dairy industry application.

Title: Device for controlling an asynchronous motor
Inventor: JEANNERET RENE
IPC: B60L11/18
Filed: 1993-06-15
Granted: 2002-08-13
Abstract: The present invention concerns a control device for an asynchronous motor, notably intended for the drive system of an electric vehicle. This control device comprises electric supply means able to produce an AC supply voltage whose frequency (FAL) and amplitude (UAL) may be adjusted independently of one another. For a given frequency of the supply voltage, the amplitude of this voltage is able to vary between a minimum value and a maximum value, the difference between the frequency of rotation of the turning magnetic field in the vicinity of the motor and the frequency of rotation of the rotor being maintained substantially constant as long as the amplitude of the supply voltage is less than said maximum value. Once this maximum value has been reached, the torque on the shaft of motor is increased by an increase of the slip.

Patent CA-2126872-C (CA)
Inventor: CARRALERO CESAR W
IPC: H03L7/18
Filed: 1993-01-27
Granted: 1999-01-12
Abstract: Certain operational characteristics of a crystal (104) are measured during a tes ting and grading process. Once determined, information representing these operational characteristics are stored in memory (120) and utilized by a controller (122) to increment a phase increment register (114) upon determining the crystals ambient temperature via a temperature sensing circuit (124). The value stored in the phase increment register (114) is then sent to a phase a ccumulator (116) where successive phase increments are summed together. This summed value is in turn sent to a sine lookup table (1 18) where the instantaneous phase value is converted into sine amplitude. Finally, a digital to analog converter (126) conv erts the amplitude bit stream into an analog signal for use as a reference oscillator frequency having extremely high frequency reso lution. The above-mentioned process is repeated every clock cycle until a complete sine wave is produced at which point the phas e accumulator is reset to zero and the process begins again.

IPC: H04B1/707
Filed: 1993-06-09
Granted: 1998-08-18
Abstract: A method and apparatus is provided for estimating signal power. The estimating is accomplished by correlating (206) an input data vector (204) with a set of mutually orthogonal codes to generate a set of output values. The input data vector (204) consists of data samples of a received orthogonal coded signal (202). Each output value corresponds to a measure of confidence that the input data vector is substantially similar to one of the orhogonal codes from within the set of mutually orthogonal coes. Finally, an estimate of the power of the received orthogonal coded signal is generated (208) as a nonlinear function of the set of output values.
Patent CA-2141547-C (CA)
Inventor: PAKETT ALLAN G
IPC: G01S13/931
Filed: 1993-08-09
Granted: 1997-06-17
Abstract: A radar system for sensing the presence of obstacles in a vehicle's "blind spots" and generating a signal (41) to the vehicle operator indicative of the presence of such an obstacle. The system uses a common radar transceiver (7) that transmits a radio fre-quency signal directed at a blind spot of the vehicle. A Doppler shift in the received reflected frequency generally indicates that an obstacle has moved into the blind spot. Doppler frequencies attrributable to objects which are of no interest, such as stationary objects, are filtered out. Only obstacles that are traveling at approximately the same speed and direction as the vehicle are consid-ered to be of interest, and will cause the blind spot sensor to generate an indication that an obstacle is present in the blind spot. The indication is preferably an unobstrusive illuminated indicator which is affixed to one of the vehicle's mirrors. An obstrusive audible indicator is provided which creates an audible tone, whistle, or buzz when an obstacle is present and the vehicle's turn sig-nal is active.
